Template Maintenance: Text threshold

Hello,

I am performing some template configuration and came across the "text threshold".

I would like to use this threshold type to filter out some database alerts which should be ignored in my organization.

For example, when Solution Manager captures the alert "this is alert xyz" from the database, is it possible to use the "text threshold" method to look for a match of "xyz" and automatically set the rating to green or ignore the alert?

I've tried operator "Contains string" and "Covers pattern" with Text Pattern "xyz" & first priority... but above alert is still appearing as warning.

Any advise is appreciated.

Thanks,
Henry
